Device for winding remaining line of optical fiber cable

ABSTRACT

A device for winding winds the remaining line of the optical fiber cable easily when wiring without lose the characteristics of the optical fiber cable.

BACKGROUND OF THE INVENTION

[0001] The present invention is related to a device for winding theremaining line of the optical fiber cable, which produced at the time ofthe optical fiber cable is wound.

[0002] The conventional winding device for the remaining line of theelectric wire is composed of a case body in the shape of a box, a holeinserted the electric wire thereinto, formed in the central uppersurface and the both-sides wall so as to insert the electric wire suchthat the electric wire passes through inside the case; and an electricwire winding drum mounted rotatably into the case, formed an electricwire insertion slot at a central part thereof, corresponding with theinsertion hole.

[0003] When the conventional device winds the remaining line of theoptical fiber cable, since the winding part to the perimeter part of anelectric wire winding drum is bent by the acute angle from the electricwire insertion slot of the electric wire winding drum, thecharacteristic of the optical fiber cable is spoiled and there is afault that it could not be used.

[0027] Preferred embodiments of the present invention are described inmore detail below referring to the accompanying drawings.

[0028] An understanding of the present invention may be best gained byreference FIGS. 1 to 8. FIGS. 1 to 8 illustrate a winding device of afirst embodiment of the present invention.

[0029] A winding device 1 winds the remaining line of the optical fibercable 2 wired and is comprises a case body 4 and a drum 5 that winds theremaining line thereof.

[0030] The case body 4 has an insertion hole 3 inserted the opticalfiber cable 2 thereinto, the insertion hole formed at a central portionof an upper surface and both side-walls of the case body 4.

[0031] The drum 5 is mounted rotatably into the case body 4, capable ofwinding the remaining line of the optical fiber cable 2 so as to notspoil the characteristic of the optical fiber cable 2.

[0032] In addition, the case body 4 is formed in the shape of a disk,and a through hole 6 is formed with a central part of an upper surfaceboard 4 a of the case body 4.

[0033] The drum 5 further includes one of winding drums 7, lower flange8, a pair of guide drums 10,10, upper flange 12, other of winding drums14, knobs 15,15, and lower guide 16 and upper guide 17.

[0034] The diameter with the winding drum 7 is at 60 mm or more; thelower flange 8 at 120 mm or more, each of the guide drums 10 and 10 at60 mm or more; the upper flange 12 at 120 mm or more, and the windingdrum 14 at 60 mm or more.

[0035] The winding drum 7 of the remaining line of the optical fibercable can be rolled round so that the characteristic of an optical fibercable 2 may not be spoiled.

[0036] The lower flange 8 is fixed to the upper surface of the windingdrum 7 so as to be located the winding drum 7 in the central portionthereof.

[0037] The guide drums 10,10 are fixed to the upper surface of the lowerflange 8 through the intervals 9.

[0038] The upper flange 12 is fixed so as to cover an upper part of theguide drums 10, 10, the upper flange 12 having a hole 11 inserted theoptical fiber cable thereinto.

[0039] The winding drum 14 of the remaining line of the optical fibercable 2 is fixed to an upper surface of the upper flange 12, the windingdrum 14 having a hole 13 inserted the optical fiber cable thereinto andprovided so as to provide with corresponding to the hole 11.

[0040] The knobs 15,15 are formed integrally at the end portion of thehole 13 except for the portion of the outer circumferential part of thewinding drum 14 so as to project upwardly.

[0041] The lower guide 16 and upper guide 17 are formed in the outercircumferential portion of the lower flange 8 and upper flange 12.Additionally, it guides one of the remaining lines of the optical fibercable 2 to the winding drum 7 and the other remaining line of theoptical fiber cable 2 to the winding drum 14.

[0042] The winding device 1 of the present invention allows the centerportion of the remaining line of the wiring optical fiber cable 2 tolocate in the recess 9 between the guide drums 10,10 after it passesthrough the insertion hole and the drum 14, and the holes 13,11.

[0043] After that, by rotating the knobs 15,15, the optical fiber cable2 is wound around the guide drums 10,10, the remaining line of theoptical fiber cable 2 is wound around the winding drum 7 and the windingdrum 14 by action of the lower guide 16 and upper guide 17.

[0044] In addition, the wound optical fiber cable 2 can be takenoutwardly by reverse-rotating the drum 5.

[0045] Other embodiments of the present invention will now be describedreferring to FIGS. 9 to 20. Through the drawings of the embodiments,like components are denoted by like numerals as of the first embodimentand will not be further explained in great detail.

[0046] A second embodiment of the present invention is shown in FIGS. 9to 11. It is distinguished from the first embodiment by the fact thatthe case body 4 is replaced from another case body 4A and an insertionhole 3A is formed in the shape of a diagonal line. The case body 4A isformed in the shape of a box. A winding device 1A with the case body 4Aaccording to the second embodiment has similar advantages to thataccording to the first embodiment.

[0047] A third embodiment of the present invention is shown in FIGS. 12to 14. It is distinguished from the first embodiment by the fact that athrough hole 18 is formed in a central part of a bottom board 4 b of thecase body 4, and a knob 19 as a rotation member is formed with thewinding drum 7. A winding device 1B in this way according to the secondembodiment has similar advantages to that according to the firstembodiment.

[0048] A fourth embodiment of the present invention is shown in FIGS. 15to 17. It is distinguished from the third embodiment by the fact thatthe winding drum 7 is fixed or formed integrally in the central part ofthe bottom surface of a rotation flange 20, and the drum 5 is replacewith another drum 5A. The drum 5A includes the guide drums 10,10, thedrum 14 and a guide piece 21 and guiding portion 22; the guide drums10,10 fixed or formed integrally on an upper surface of the rotationflange 20; the drum 14 fixed or formed integrally on an upper surface ofthe rotation flange 20 and having a insertion hole 13 corresponding tothe intervals between the flange drums 10; and the guide piece 21 andguiding portion 22 guiding the remaining line of the optical fiber cable2 to the drums 7 and 14 from the drums 10,10. A winding device IC inthis way according to the second embodiment has similar advantages tothat according to the first embodiment and the number of parts isreducible.

[0049] A fifth embodiment of the present invention is shown in FIGS. 18to 20. It is distinguished from the third embodiment by the fact thatthe case body 4 is replaced from another case body 4B formed in theshape of a box, the case body 49 having concave portions 23,23 forreceiving an optical connector provided at the both side walls of theinsertion hole 3. The optical connector of the optical fiber cable woundcan be contained the concave portion 23,23 of a case body 4B. Inaddition, the concave portion 23,23 formed in the case body 4B may beformed in one sidewall of the insertion hole 3

[0050] In addition, in each of embodiments of the present invention,although the drum 5 is rotated by hand, the drum 5 may be woundautomatically by using a swirl spring etc. when winding. In this case,the torque of a swirl spring allows to lock and to lock release.
